KNooKDowN CONTAINER.

To all whom tmay concern.'

Be it knownl thatl, JOHN citizen of the United States, and a resident ofChicago, in the lcounty of Cook and State of illinois, have inventedanew and useful which the following is a full, clear, andexactydescription.

My invention relates to knock down containers, and'it consists in thecombinations7 constructions, and arrangements herein described andclaimed.

An object of my invention'is to provide a knock-down containercomprising relatively few parts which are inter-engaged vto main` tainthe containerv in set-up or assembled condition. v A further object ofmy invention is to provide a device of thetype described that is simplein construction and operation, not likely to get out of order easily,and thoroughly practical commercially. A further object of my inventionis to provide a device of the type described that can be disassembledand the parts thereof packed to occupy a comparatively small space,wherefore `the containers when empty may be readily conveyed from placeto place and used repeatedly.

`A further object-of invention is to is light invweight, strongandmdurable, Aand capable of being produced in large'quantities quicklyand cheaply; f,

Other objects and advantages will appear in the followingspecificatiomand the novel features ofthe invention will be particularlypointed 'out in the appended claims.

My invention is illustrated'in the accompanying drawings, forming partof this application in which Figure l is a side elevation,partly brokenaway `and in section, of an embodiment Yof my lnvention,

Figure 8 is a side elevation, partly broken away and in section of stillanother moditied form ofthe device,

Figure-9 is a detail view of a developed fragmentary portionofthe formofthe device shown in Fig. 8.

- Reference is to be had to the drawings in which like referencenumerals denote like parts throughout the several views.

In Figure 1, a substantially cylindrical body portion is denoted'by l.This body portion in its developed form comprises a single platewhich ispreferably` formed of metal, but may be made of any suitablematerial,such as liber, or the like. The upper vand lower ends of thebodyrportion-lare each bent outwardly at 3-3 and then down-v wardly andupwardly7 respectively, thus providing the overlying stiffeningniember2-2 A retaining member l that is vbent into U-shape is secured at 5, asby welding, f

to the' bodyportion along one side yedge thereof and is adapted toreceive the other side edge of the body portion when the latter n tralportion@ and a substantially lil-shaped marginalportion 9 adaptedtoreceive a rim edge of the body portion 1 and to have its outerwallflli overlapping a portion ofthe 'body portion l adjacent the end.Thestraps 7 are then' bent around the lower edges of'one of theoverlying stiffeners 2 and the outer wall 14o-f the head or cover and'upwardly at 10,

f then inwardly at ll, downwardly at yl2 tinto contact withthe depressedcentraliportion 8,v and theninwardly at 13 to overlap `the centralportion 8, as bestseen in Figure l.

' From the foregoing'description of the various parts of the device,theoperationthereof maybe readily. understood. It will be seen that thevprovision of the overlying stiffeners 2 2 and the arrangement oftheheads or `covers relative the body portion 1 strengthens the containerat the points at which stress is likely to be applied inservice.Furthermore, the cover portions or heads are maintained in the positionsshown by the engagement of the saine'withth'e cylindrical body portionand by the straps Twhile Valso serving to maintain the straps in operaytive position. That is, the parts of the device not only serve theirobvious functions, but also co-act to maintain the container inassembled or set-up condition, wherefore the device is very strong anddurable and not likely to be impaired when subjected to the shocks andjars incident to its service.

One of the heads or cover portions may be secured in position and thecontainer then filled. The other head or cover is then secured inposition and the device is ready for shipment; `When not in use, thedevice may be" disassembled and the parts thereof packed to occupy but asmall space and secured in packages which may be stored away or readilytransported from place to place at a relatively low cost. The fasteningstraps 7 may be discarded when the container is emptied,

since their construction isA such that they may be replaced readily at alow cost. Referring now to Figure 8, I show a somewhat diiferent meansin the same device for simil-ar to the body portion 1.

angles to each other, have their ends projecting through the openings20. Cover portions or heads such as have been described are placed inposition on the body portion 19'and` the projecting` portions ofthestraps 2l are bent upwardly, or downwardly, as the case may be, at22, inwardly at 23, and upwardly or downwardly at 24 aroundl the U-shaped marginal portion 9 of the head and into engagement with thedepressed central portion thereof. The straps are 'finally bent inwardlyat 25 adjacent their ends to overlap the depressed central' portion 8.The cover portions are therefore securely held in position.

Referring now to Figure 4 in which another embodimentof the sameinvention is illustrated, it will be noted that I provide a cylindricalbody portion 3() that is similar to the body portion 19. I make -use ofthe fastening straps 21 which project through diametrically opposedopenings 31- in the walls of the body portion 30 adjacent the endsthereof and are bent around the edges of the body portion 30, asdescribed, into engagement with heads 32 which in this form of thedevice consists of circular disks whose outer edges contact with theinner walls of the body portion 30 adjacent `the ends thereof.

Referring now to Figure 5, there is illustratedithe'r'ein a form of thedevice having a body portion 4() that is identical in essential respectswith the body portion 19. Cover portions or heads, such as described,are provided and maintained in position relative the body portion 40 inthe manner described;

`It is desirable that containers embodying my invention ,and intended tobe used for certain purposes should be provided with abail or handle topermit the same to be readily carried from place to place. I thereforeprovide detachable means for securing the handle to the container whendesired, such means comprising straps each bent at 41 or intermediateits length, one portion thereof being` bent at 42 and 43 around the edgeof the marginal portion 14 of the cover and then at 44 around the edgeof the body portion. The other portion of the strapv` is bent at 46 and47 around the U-shaped portion 9 of the cover or head and intoengagement with the depressed central portion 8 there` of. It will beunderstoodthat two of these straps or bars are provided and that thesame are secured to the container in the manner described atdiametrcally. opposite points. The ends of a bail or handle 48 aresecured at 49 to the outstanding lug portions of these straps. y .i

lreferring now to Figures (5 andy T, l( show. two inodilied forms of thebody portion 1*. In the forni shown in Figure A(i, the body portion isformed of four arcuate similar sections 50, 51, 52, and ,53p The sideedges of the section 59 are bent outwardly and then toward each other at505-@L toL forni fins or tongues 50h-50", yIn 'ai like manner. thesections 511, 52, and I53 have theirsides bent at 31a-51, 52-52a, andfL-B to forni fins or tongues Sib-51?, 52h-45,2?, 'and 53b-53b,i'espectively. Reenforcing clips' 54, each provided with opposed groovesor pockets 55 and 56 adapted to receive the tongines formed integrallywith acentportions of the several sections,maintainthesections'assemble-d to formthe substantially cylindricalbody portion illustrated, which is also strengthened by the provisionofthe reenfoi'cing clips 54. In Figure 7, the -foim of the body portionillustrated comprises' a single plate GO'having its oppositefsides bentadjacent the edges thereof at (51l and G1" to provide the fins 61 andG2, respectively. A fastening clip 63 having opposed grooves k orpockets 64 andv 65 is adapted to receive' the ymay be fitted with anyone of theseveral heads or cover portions described.;l

Referring now to Figures 8 and 9, a body ilo portion is made up ofsections which are identical in essential l respects with those shown inFigure 6vand consequently require .no further description. A fragmentaryporyondthe ends of the flaps 7l and is divided into three segments 74, 75, and v7 6. yThe segments and 76 are bent over the ends oit thecontainer 70, thus preventing longitudinal movement of the clip withrespect tothe container'. The iiaps 71 forni pockets which receive theportions of thesections in the container 70, in the same manner as theportions 61 and 62 are received in the grooves 64; and 65 (see Figure 7The covers 8 may no-'W be disposed over the completed container 70 andare held in place by the segments 7 4l which are bent thereover in themanner illustrated in Figure 8. l

rlhe device may be used in the same manner as an'ordinary container,since it may be readily separated' into itsparts and has the advantageof being readily transportble at a lowcost When disassembled.
